If all goes well, today's Spring Training action will feature Zack Greinke's return to the mound as the Dodgers take on the D-backs in Glendale, Ariz.

Greinke, who sustained a mild calf strain in his first Cactus League start on Feb. 27, participated in pitchers' fielding practice and other drills Tuesday, and he is penciled in to start Los Angeles' 4:05 p.m. ET contest, which streams live on MLB.TV. Should Greinke be held back, Zach Lee will start in his place. Los Angeles will face one of Arizona's Minor League pitchers, as the D-backs send Wade Miley to face the Rockies in the club's other Wednesday contest.

In Port St. Lucie, Fla., the battle for the Cardinals' fifth rotation spot continues as right-hander Carlos Martinez takes the mound at 1:10 p.m. ET on MLB.TV. He will face the Mets for the second time in six days, having limited New York to one hit in three scoreless frames last Friday. Opposite Martinez, Mets lefty John Lannan will make what could be one of his final spring starts as the club considers shifting him to a bullpen that currently features only one left-hander.

In one of their split-squad road matchups Wednesday, the Nationals head to Kissimee, where rookie manager Matt Williams will get his first taste of expanded instant replay in a 1:05 p.m. ET game against the Astros on MLB.TV. Tanner Roark will take the ball for the Nats, while Astros right-hander Jerome Williams will make his first Grapefruit League start. Williams surrendered a pair of runs on five hits through 4 2/3 innings of relief this spring.

The Tigers will also get their first experience of expanded replay as they travel to Tampa to face the Yankees in a 1:05 ET contest on MLB.TV. Detroit's Anibal Sanchez will toe the rubber at Steinbrenner Field for the second time in six days, starting opposite New York's Hiroki Kuroda, who inked a one-year, $16 million deal in the offseason. The 39-year-old right-hander will look to continue his strong Grapefruit League showing, as he has yet to allow a run through 4 2/3 innings this spring.

After their first of two off-days this spring, the Bucs will resume play Wednesday, meeting the Twins in Ft. Myers. Pittsburgh will send second-year hurler Gerrit Cole to the mound in the 1:05 p.m. ET game, and the righty could swing the bat for the first time this spring, as the Pirates tentatively plan to have its starters hit to begin simulating regular-season play. For Minnesota, Kevin Correia is scheduled to start in his second Grapefruit League appearance.

Also off Tuesday, the Brewers return to the diamond in Tempe, Ariz., sending offseason acquisition Matt Garza to the mound against the Angels at 4:05 ET. Garza passed on a four-year, $52 million deal from the Angels in December to sign a similar deal with Milwaukee. Hector Santiago will start for Los Angeles, as the club separates for split-squad games on Wednesday.

San Diego's Tyson Ross will look to continue his scoreless-innings streak as he gets the start against the Indians at 4:05 ET on MLB.TV. Ross, expected to throw four innings and around 60 pitches, has yet to allow a run in five frames of work this spring. For Cleveland, Corey Kluber will make his fourth Cactus League appearance. The right-hander has surrendered three runs (two earned) on four hits through six innings this spring.

Wednesday's MLB.TV slate concludes with the Cubs and Mariners in Peoria at 10:05 p.m. ET. featuring a pair of free-agent acquisitions on the mound. James McDonald, who signed with Chicago last month, is making his second spring start, while the Mariners will send another veteran non-roster invitee, Randy Wolf, to the hill. After missing most of last season following Tommy John surgery, Wolf has allowed four earned runs on four hits in two spring starts (five innings) with his new club.
