Dbacks ref and notes

Gallen (1-4) took the loss against Texas on Tuesday, tossing 4.2 innings during which he allowed seven runs on seven hits and two walks while striking out four batters.

Gallen struggled from the outset, serving up a solo homer to Joc Pederson in the first inning. He trailed 3-0 entering the fifth, then got just two outs in that frame while being charged with four more runs. Gallen managed just six whiffs among his 95 pitches and has now given up a combined 17 runs over his past three starts spanning 14.1 innings. That has pushed his season ERA up to an ugly 5.65.

The Diamondbacks acquired Requena from the Dodgers on Tuesday in exchange for Alek Thomas, Francys Romero of BeisbolFR.com reports.

Requena was just signed in January to a $372,500 bonus and has yet to make his professional debut. The 17-year-old is a lottery ticket for the Diamondbacks.

Vargas went 0-for-4 in Monday’s 1-0 win over Texas.

Vargas, who opened the season with a 24-game hitting streak, was held hitless for a second consecutive game and is just 5-for-36 (.139) in the nine games since the hit streak ended. A regression was to be expected, but that won’t cost him the starting job at first base. The Diamondbacks announced Monday that Carlos Santana aggravated his adductor injury Sunday and will not be returning this week to challenge Vargas for playing time.
