Logan Gilbert made a wild catch on Wednesday. Just with the wrong tool.

In the first inning of a game against the Athletics, the Seattle Mariners right-hander got a 107.8 mph comebacker off the bat of Carlos Cortes. The ball arrived before Gilbert could react and ended up nestled inside Gilbert’s jersey.

Much to the confusion of Gilbert.

So that’s a catch, right? Because the ball never hit the ground? Unfortunately, no.

From the official MLB rulebook, here’s the comment that addresses this exact situation:

So you can only use your hand or glove to catch the ball. Therefore, the play was ruled a single for Cortes, which loaded the bases with no outs.

That wound up being costly for Gilbert, who saw two runs score on a sacrifice fly from Tyler Soderstrom and RBI single from Jeff McNeil that also included a fielding error by center fielder Julio Rodríguez.

Gilbert finished his day with 4 innings pitched, 6 hits allowed, 3 runs (all earned), 2 walks and 3 strikeouts on 89 pitches.
