A’s Finally Get on the Board, Sign Jace Peterson as Veteran Jack of All Trades

The A’s have made no secret of their intentions to spend as little as possible. Per Spotrac, they entered the offseason with a grand total of zero guaranteed dollars of active payroll, outside of arbitration and pre-arb salaries. Of the 39 players on their 40-man roster, only four are arb-eligible, and Tony Kemp, with all five years and 98 days of big league service time, is by far the most-tenured player on the team. They’ve traded nearly every productive major leaguer over the past calendar year for prospects and players making the minimum. But at the Winter Meetings, Oakland finally made its first signings of the offseason, agreeing to terms on two-year deals with utility player Jace Peterson and former Astros utility man Aledmys Díaz, the latter worth $15 million.
Originally drafted by the Padres in 2011, the 32-year old Peterson has made plenty of stops throughout his career, from Atlanta to New York and Baltimore; he spent the last three seasons with the Brewers before becoming a free agent this offseason. In 2022, he appeared in 112 games, starting 81 of them. Utilized almost exclusively as a platoon player, he racked up 293 plate appearances against right-handed pitchers, only stepping into the box 35 times against lefties. His primary platoon partner this year was Mike Brosseau, who posted a 117 wRC+ in 160 PA, about two-thirds of which came against southpaws. Peterson came up as a second baseman but has spent the bulk of his career as a super-utility player, in most seasons making starts at first, second, third, and both corner outfield spots. This year with the Brewers, he primarily played third base, making 67 starts there as everyday players took the bulk of playing time at the other positions he has usually manned.
Peterson’s biggest strength on the offensive side has been his disciplined approach at the plate. During his three-season stretch with the Brewers, he walked in 12.4% of plate appearances, and his 24.6% chase rate ranked in the 90th percentile among major league hitters, placing him in company of Joey Votto and Mookie Betts. He’s affectionately earned the nickname “On Base Jace” (he’s had three postseason plate appearances and drew walks in all of them) and slashed .238/.337/.373 with a 98 wRC+ during his time in Milwaukee. While his raw power grades out at about average, he has never hit double-digit homers and has a below-average ISO for his career, largely because he hits more ground balls than average and doesn’t pull the ball at a high rate. Despite these middling offensive numbers, he’ll likely slot into the heart of an Oakland lineup that had just two hitters with at least 300 PA and an above average wRC+, and with backstop Sean Murphy likely on the move in the near future, that list is cut to just Seth Brown.
