Short was designated for assignment by the Red Sox on Wednesday.

Advice: Short is being swapped out in favor of Romy Gonzalez, who is retuning from the injured list. He played in just two games for the Red Sox, going 0-for-7 with four strikeouts. Rotowire.com 57 minutes ago

Espinal will start at third base and bat fifth in Wednesday's game against the Diamondbacks.

Advice: Espinal saw a streak of six consecutive starts come to an end in Tuesday's 6-2 loss to Arizona, and before that, he enjoyed a stretch of 11 consecutive starts. He looks as though he could fall into regular playing time once again, as the Reds placed Christian Encarnacion-Strand (wrist) on the 10-day injured list Wednesday. Jeimer Candelario will move over from his usual spot at third base to cover Encarnacion-Strand's post at first base, opening up the hot corner for Espinal. Despite seeing plenty of usage in his utility role this season, Espinal has provided the Reds with underwhelming numbers (.169 average, one home run, four stolen bases, 12 RBI and five runs) across 90 plate appearances.

Newman will start at shortstop and bat ninth in Wednesday's game against the Reds.

Advice: Newman will make his third straight start at shortstop -- all against right-handed pitching -- and looks to have supplanted Blaze Alexander as the Diamondbacks' preferred option at the position while the team waits for Geraldo Perdomo (knee) to return from the injured list. Though he's turned in a poor .559 OPS through 62 plate appearances with Arizona this season, Newman has been a much more polished defender at shortstop than Alexander. Rotowire.com Today, 12:18 pm

Hernaiz, who was placed on the 10-day injured list earlier Wednesday, has been diagnosed with a severe left ankle sprain and will visit with a foot specialist, Martin Gallegos of MLB.com reports.

Advice: Hernaiz was injured during Tuesday's 15-8 loss to the Rangers when he stepped awkwardly on first base and was subsequently placed on the IL. More should be known about a potential timetable for the rookie infielder following his exam, but Hernaiz looks as though he could be sidelined for weeks, if not months. The 22-year-old has slashed .182/.243/.182 over 75 plate appearances with Oakland this season and had recently been serving as the team's everyday shortstop. Rotowire.com Today, 11:22 am

Diaz (calf) ran the bases at Oakland Coliseum on Wednesday, Martin Gallegos of MLB.com reports.

Advice: Diaz has been out since late February, first with a groin injury and more recently a calf strain. That he's been cleared to run the bases signals that he shouldn't be too far off from a rehab assignment. Diaz is on the 60-day injured list, so he won't be eligible for activation until late May.
