Scanning baseball’s statistical leaderboards for the 2016 season will tell you the players who turned in the best or worst performances last year. But, for some context, I’ve looked at some of those leading players to consider the significance of their accomplishments over a longer period than just last season. For example, you probably weren’t aware that Bryce Harper‘s .243 batting average last year was the lowest by a player leading his league in IBB, breaking the old mark of .249 by White Sox catcher Ed Herrman in 1972.

More on last season’s statistical leaders after the jump.

Mike Trout reached 48.5 WAR for his career, the highest total ever by age 24. Trout also holds the same record for ages 20, 21, 22 and 23 (old record: Ty Cobb age 22-24, Mel Ott age 20-21). Trout’s 5 seasons with 100 runs scored are also a record by age 24, tied with Alex Rodriguez.

David Ortiz‘s 5.1 WAR is the highest mark in the final season of a career (excluding Black Sox players). Ortiz also shattered the record book for any age 40+ season with these marks (showing Ortiz/previous record) in home runs (38/34), doubles (48/33), extra-base hits (87/62) and RBI (127/108). Ortiz led his league in the latter three of those four categories and in SLG and OPS, becoming the oldest league leader for all five.

The Seager brothers combined for 13.0 WAR (6.9 for Kyle, 6.1 for Corey), the most in a season for two brothers, breaking the mark of 12.8 by Joe (9.1) and Vince (3.7) DiMaggio in 1941.

Brian Dozier became just the fourth AL second baseman to record a season with 80 extra-base hits (there are also four NL second baseman who have done this). Even before his career best 42 home runs last season, Dozier established a new career home run record for Senator/Twin second basemen with his first blast of 2016, a month shy of his 29th birthday.

Mookie Betts became the second Red Sox player aged 23 or younger to reach 350 total bases in a season. The surprise is that the first one was Nomar Garciaparra and not Ted Williams, as the Splinter had four seasons that young with 330 total bases.

Jose Altuve and Starlin Castro, both aged 26, surpassed 1000 hits for their careers. The only other expansion era seasons with a pair of players 26 years old or younger who had reached that milestone are 2003 (Edgar Renteria and Andruw Jones), 1982 (Garry Templeton and Robin Yount) and 1966 (Ron Santo and Carl Yastrzemski).

Robinson Cano‘s 7.3 WAR is the most in the expansion era by a second baseman aged 33 or older, but only the 8th highest WAR total since 1901 by second basemen that old. Cano became just the 10th second baseman to reach 60 WAR by age 33; eight of the other nine are in the HOF.

Nolan Arenado followed Chuck Klein to become just the second player aged 25 or younger to record two seasons with 40 home runs, 40 other extra-base hits, and three times as many RBI as home runs. Lou Gehrig (5), Jimmie Foxx (3) and Duke Snider (3) are the only players with more such seasons for their careers.

Josh Donaldson recorded his fourth straight 7 WAR season, joining Mike Schmidt, Wade Boggs and Ron Santo as the only third sackers with that four-peat. Donaldson’s 2015 season with both 120 runs and 120 RBI had been matched as a third baseman only by Alex Rodriguez (2005, 2007) and Lave Cross (1894).

Daniel Murphy‘s .595 SLG is the highest expansion era mark to lead the NL by a player with 25 or fewer home runs. Dave Parker (1975) is the only other expansion era player to lead the NL in SLG in such a season, compared to six such seasons in the AL. For the second time in three years, both league slugging champions failed to score 90 runs (AL champ David Ortiz didn’t reach 80), something that had happened in only two full-length live ball era seasons (in 1968 and 1991) before 2014.

Nelson Cruz became the third player with three 40 home runs seasons aged 33-35, joining Mark McGwire and Babe Ruth. Cruz is also in a leading group of three players with three straight seasons after age 30 with 40 home runs and less than 6 WAR, joining Frank Howard (1968-70) and Andres Galarraga (1996-98).

Joey Votto led the NL in OBP for the 5th time, and recorded a .400 OBP with 90 walks for the 6th time in his career, the latter mark setting a new Reds’ record, one season more than Joe Morgan. Votto also combined 100 runs and 100 walks with fewer than both 30 home runs and 10 stolen bases to become just the fifth player to post three such seasons.

AL home run champ Mark Trumbo posted career highs in Runs, Hits, Home Runs, RBI, SLG and OPS. But he and NL home run champ Chris Carter both slugged under .550 (Carter was under .500), the first pair of home run champs with 40+ dingers to fail to clear that slugging mark. In all, six players in 2016 recorded 40 home runs but failed to slug .550, twice as many as the next highest total of three players, recorded one season earlier in 2015.

Kris Bryant recorded 25 home runs, 30 doubles and 75 walks to become the first player to do so in each of his first two seasons (he’s also the first player to post those totals in his rookie season and the next). Bryant also batted .275 with 150 strikeouts in each of those two seasons, again a first, and halfway to catching Sammy Sosa for the most such seasons in a career (to do so, Bryant will need to outlast Paul Goldschmidt and Mike Trout, who also have two such seasons, as do fellow active players Shin-Soo Choo, Matt Kemp and Nelson Cruz).

Albert Pujols recorded 119 RBI, his best total since turning 30 and the 15th time in 16 years that he’s recorded at least 95 RBI, two seasons more than any other player over that part of a career. Bill James’ Career Projection tool sees Pujols playing three more seasons and reaching 2143 RBI, with only an 18% chance of tacking on the 155 more RBI needed to surpass the 2297 total of all-time leader Hank Aaron. On the immediate horizon, though, is becoming the third player, after Aaron and A-Rod, to reach 600 doubles and 600 homers, as Pujols needs just 9 more dingers to join that group. Pujols is the 6th player to reach 1600 runs and 1600 RBI over his first 16 seasons, and needs just 30 more runs next year to keep pace with the group and maintain that century average over his first 17 seasons. In 2018, 3000 hits could be in his sights (James sees Pujols reaching 3296 hits, with a 97% chance of making 3000, and a 45% chance to crack the top 10 with a total of 3320 or more).

Rick Porcello recorded his eighth qualified season with BB/9 under 3.0. Among expansion era hurlers, only Bert Blyleven has more such seasons by age 27. Porcello’s .846 W-L% was more than double his 2015 mark, becoming the first live ball era pitcher to follow a sub-.400 W-L% season with an .800 W-L% season, both in 20+ decisions (Bobo Newsom is the only live ball era pitcher to go in the other direction, with a 21-5 mark in 1940 and 12-20 in 1941).

Max Scherzer led his league in Strikeouts, Wins and HR allowed, to join Robin Roberts (1954) as the only live ball era pitchers with that trifecta. Scherzer is just the 9th pitcher since 1901 with a .700 W-L% in 100+ decisions aged 26 to 31. Of that group, only Scherzer and Lefty Grove posted a W-L% under .500 in 20+ decisions through age 25.

Jeurys Familia pitched in 75+ games to join Mitch Williams as the only pitchers with three such seasons by age 26. Familia’s 51 saves led the NL, making it 6 years in a row that the NL saves leader recorded a season with more games than IP. For the AL, it’s 10 straight years that the saves leader has failed to average an inning per appearance.

Jake Arrieta won two-thirds of his decisions for the third straight season, during which his 2.42 ERA was second only to Clayton Kershaw‘s 1.89 mark among pitchers with 400 IP for those seasons. That 2.42 ERA is also lowest, by more than a run and a half, of eleven pitchers with 400 IP aged 28-30 after posting an ERA over 5.00 in 400 IP before age 28.

David Price started 35 games, the first pitcher to do so since 2010. As many as 18 pitchers recorded 35 or more starts as recently as 1996, and 12 pitchers recorded 40 or more starts as recently as 1973 (Charlie Hough, at age 39 in 1987, is the last hurler with a 40 start season).

Chris Sale recorded 5 complete games that were not shutouts (and one that was). That’s the highest total since 2012 and ups Sale’s career totals to 14 CGs but only two shutouts. That 7:1 ratio is the highest among 30 active pitchers with 10 career CGs, with David Price (16 CG, 3 SHO) the only other pitcher with a ratio over 4:1.

Josh Tomlin recorded his second qualified season and, as he did in 2011, led the majors in BB/9. In doing so, Tomlin becomes just the fifth expansion era pitcher to post a pair of qualified seasons with BB/9 under 1.2 and SO/BB under 6.0, and the first to do so in his first two qualified seasons.

Noah Syndergaard led the majors with the best HR/9 and FIP results. At age 23, Syndergaard is the youngest pitcher with that accomplishment since the Dodgers’ Bill Singer in 1967 (also aged 23).

Kyle Hendricks led the majors in ERA and ERA+ while posting a SO/BB ratio below 4.00. At age 26, Hendricks is the youngest pitcher with that accomplishment since Toronto’s Jimmy Key in 1987 (also aged 26). In that period, only Roger Clemens (twice) recorded that feat at any age.

Brad Hand, in his first season as a full-time reliever, led the majors with 82 games pitched and joined a group of 98 relievers with ERA under 3.00 and 130 ERA+ in an age 26 season of 75+ IP. Of that group, Hand’s 81 ERA+ through age 25 is second worst among those with 250 IP over that part of their careers. Hand’s career to date is eerily similar to that of John D’Acquisto, the pitcher in that group with the worst ERA+ through age 25. Like Hand, D’Acquisto’s fortunes brightened after moving to San Diego where, again like Hand, D’Acquisto was first used primarily as a reliever.

So what other weird and wonderful nuggets have you uncovered about last season’s play?
