Former Red Sox relief prospect Marques Johnson ended the first full season of his professional career on a strong note by earning California League Pitcher of the Week honors on Monday.
Johnson, who the Red Sox traded to the Giants for fellow reliever Mauricio Llovera in late July, made two appearances for San Francisco’s Low-A affiliate in San Jose in its most-recent series against the Stockton Ports. The right-hander struck out 10 and walked only one of the 17 batters he faced over five scoreless, one-hit innings of relief.
After joining the Giants organization ahead of the trade deadline, Johnson closed out the 2023 campaign by pitching to a 0.00 ERA and 3.40 FIP with 20 strikeouts to nine walks across 11 outings (18 1/3 innings) for San Jose in which he held opposing hitters to a .145 batting average against. He also converted his lone save opportunity, which came in a 14-1 win over Stockton on Friday.
A native of California himself, Johnson was selected by the Red Sox in the 11th round of last year’s draft out of Long Beach State. He signed with Boston for $122,500, but did not make his pro debut with Low-A Salem until this April. As a member of the Salem Red Sox, the 23-year-old righty posted a 6.55 ERA with 43 strikeouts to 24 walks over 28 appearances (34 1/3 innings) out of the bullpen.
While that ERA is far from eye-popping, Johnson produced a far more favorable 3.75 FIP with Salem. He had also been pitching much better in the weeks leading up to the trade, yielding just one earned run in his final seven appearances (9 2/3 innings) for Boston’s Carolina League affiliate. It appears as though those results carried over into the California League and Johnson now has some hardware to prove it.
Standing at 6-foot-2 and 210 pounds, Johnson throws from a three-quarters arm slot and operates with a three-pitch mix that consists of a 93-96 mph fastball that tops out at 98 mph and features high spin rates, an 83-85 mph slider, and an 86-88 mph changeup, per his SoxProspects.com scouting report.
Johnson, who does not turn 24 until next July, possesses intriguing potential if he can further refine his control and command of the strike zone. And while San Jose’s regular season is over, the Giants are slated to open a three-game playoff series on the road against the Modesto Nuts on Tuesday.
