Ross and Vincent are each 33-year-old righties who had inked minor-league deals in the offseason. The former is best known for his days in the Padres rotation. The latter, a reliever, was also once an effective hurler in San Diego as well as with the Mariners.
Though he struggled in limited big league action last year, and has never recovered from serious shoulder injuries, Ross has a lifetime 4.04 ERA in ten MLB campaigns. He didn’t have much hope of cracking the starting staff, but was perhaps a multi-inning relief candidate. Ross struggled in his three outings in camp before the pandemic paused the action.
As for Vincent, he struggled with the long ball during a stint with the Giants last year. But he turned in a strong 14-inning run to end the season — 1.93 ERA with 17:4 K/BB — with a Phillies team that was managed by new Giants skipper Gabe Kapler. Vincent had coughed up three homers and seven earned runs in four Spring Training frames.
Westbrook has yet to appear in the majors, having reached minor league free agency after seven seasons in the Diamondbacks system. He turned in 514 plate appearances of .281/.358/.451 hitting in the upper minors last year, but obviously didn’t show enough in camp for the Giants to keep him in their 60-man player pool.
