Grant McCray

The Giants announced they’ve selected outfielder Grant McCray onto the major league roster. San Francisco optioned Marco Luciano back to Triple-A Sacramento in a corresponding move. The Giants already had an opening on the 40-man roster.

They’ll use it to take their first look at McCray, whom they drafted out of a Florida high school in 2019. The former third-round pick is starting in center field tonight against Braves righty Grant Holmes. McCray can play all three outfield positions and has spent the vast majority of his minor league time up the middle.

That defensive acumen is McCray’s biggest appeal. Prospect evaluators credit him with plus or better speed and an excellent arm. He has the tools to be a plus defender in center field. Outfield defense has been an issue for the Giants for a few seasons. That’s particularly true in center, where Heliot Ramos has been the starter lately. Ramos has had a breakout year offensively but is clearly stretched playing up the middle. Most scouting reports have long pegged him as a corner outfield fit. Both Defensive Runs Saved and Statcast’s Outs Above Average have graded him harshly in his 493 innings of center field work this year.

Ramos moves to left field tonight, pushing Michael Conforto to designated hitter. If McCray is up as an everyday center fielder, that’ll probably have the biggest impact on Jerar Encarnacion’s playing time. The Giants have given him five starts apiece at DH and in the corner outfield since they selected his contract on August 2. He’s hitting .237/.293/.395 over 41 plate appearances. McCray playing center field would leave the corner outfield/designated hitter roles to some combination of Ramos, Conforto and Mike Yastrzemski on most days.

The long-term viability of that plan probably depends on how well McCray acclimates to big league pitching. Scouting reports at Baseball America and FanGraphs credit him with nascent raw power but have never been bullish on his pure hitting ability. McCray has turned in decent results between the top two levels of the minors this year, combining to hit .242/.330/.446 in 97 games. He has 12 homers, seven triples and 26 doubles through 421 plate appearances.

McCray is drawing walks at a strong 10.7% clip but has fanned in nearly 29% of his trips. Strikeouts have been a problem throughout his minor league tenure. It’ll be a challenge for him to make contact in his first look at big league pitching, but his combination of power and athleticism present some upside if he can put the ball in play somewhat regularly.

Strikeouts have also been a question for Luciano, who has long been one of the Giants’ top prospects. San Francisco initially planned to give him everyday run at designated hitter after the Jorge Soler deadline trade. They backed off on that fairly quickly, perhaps because of trepidation about his elevated strikeout tallies in the upper minors and his limited look (31 games over two seasons) against MLB pitching. Luciano scuffled defensively at shortstop and has yet to really find a position at the MLB level. He’s still just 22, so the Giants will get him consistent reps in Triple-A to continue his development on both sides of the ball.

The Giants have dropped three straight to fall back to .500, though they’re only 3.5 games behind Atlanta in the Wild Card race. They’re playing the Braves tonight and tomorrow in what could be pivotal games.
