The Athletics traded outfielder Cal Stevenson to the Giants in exchange for cash, per announcements from both teams. Oakland had designated Stevenson for assignment late last week. San Francisco designated lefty Sam Long for assignment to open a spot on the 40-man roster. Stevenson has been optioned to Triple-A Sacramento.
Stevenson, 26, appeared in his first 23 big league games with Oakland last year but managed only a .167/.261/.217 output in 71 plate appearances. Oakland picked him up alongside minor league righty Christian Fernandez in a trade that sent catcher/first baseman Christian Bethancourt back to Tampa Bay. Thus far, that hasn’t panned out in the A’s favor, though Fernandez is out to a nice start in High-A this season.
Stevenson has been an on-base machine in the minors, with more walks (240) than strikeouts (222) through 1471 minor league plate appearances. He’s spent parts of two seasons (2023 included) at the Triple-A level and posted a combined .289/.397/.414 batting line, showing plus plate discipline and bat-to-ball skills but minimal power. He’s never turned in a double-digit home run total in a professional season, though he did pop nine long balls in an injury-shortened 2021 Double-A campaign that saw him tally just 365 plate appearances. He has ample experience in both center field and in left field. Stevenson also has two minor league option years remaining (2023 included).
As for Long, the 27-year-old southpaw has spent parts of the past two seasons in the Giants’ bullpen but opened the 2023 campaign in Sacramento, where he’s gotten out to a rough start. Through 10 Triple-A innings, Long has been tagged for 11 runs on the strength of 14 hits and five walks with just seven punchouts.
Long tallied a career-high 42 1/3 Major League innings last season with San Francisco, pitching to a 3.61 ERA with a sharp 7.7% walk rate but a well below-average 18.2% strikeout rate. He averaged 94.5 mph on his heater but was also exceptionally homer-prone despite a spacious home park, serving up an average of 1.70 big flies per nine innings pitched. Metrics like FIP (5.07) and SIERA (4.31) felt he had some good fortune to keep his ERA so low, which is likely the case to some degree, given a fairly low .248 average on balls in play.
This is Long’s final minor league option year, so he can freely be shuttled between Triple-A and the big leagues for the remainder of the season but not in 2024. The Giants will have a week to trade him or attempt to pass him through outright waivers.
