Former big leaguers Seth Beer and Mark Mathias signed with the Long Island Ducks of the Atlantic League this week. The team announced both signings.
Beer, 28, was a first-round pick by the 2018 Astros who wound up being one of four players traded to the D-backs in the last-minute deadline blockbuster that brought Zack Greinke to Houston in 2019. The first baseman/designated hitter appeared in parts of two seasons with Arizona, hitting a combined .208/.294/.292 in a small sample of 136 plate appearances from 2021-22.
Though Beer hasn’t found much success in the big leagues, he’s a fairly accomplished hitter in Triple-A, where he’s slashed .262/.365/.463 with 40 homers across 1093 plate appearances in parts of four seasons. He’s walked at an above-average 9.3% clip there and has kept his strikeouts to a manageable 18.8% rate. The lefty-swinging slugger spent the 2024 season in the Pirates system, where he hit .277/.354/.431 in a combined 99 games between Double-A and Triple-A.
Mathias, 30, has a good bit more major league service time under his belt — more than two years’ worth — but much of it has been spent on the injured list. He’s suited up for the Brewers, Pirates, Rangers and Giants in a utility capacity, hitting a combined .246/.317/.391 in 199 plate appearances spread over 73 games. Injuries have been a major detriment to the former third-round pick’s career. He’s undergone two shoulder surgeries: one in college and another in 2021 to repair a torn labrum. That second procedure cost him the entire 2021 season.
As with Beer, Mathias has a strong Triple-A track record but more modest big league numbers in scattershot playing time. He’s a .288/.383/.454 hitter in three Triple-A campaigns, during which he’s tallied 919 plate appearances. Mathias has walked in an impressive 12.8% of his Triple-A plate appearances against a 21.5% strikeout rate. He’s spent the bulk of his pro career at second base but has more than 1000 innings of work at third base in 200-plus innings at shortstop and in the outfield corners.
