Diaz was optioned to Triple-A Indianapolis on Thursday.

Diaz finds himself behind Francisco Cervelli and Chris Stewart on the depth chart heading into the 2017 season, so the Pirates will send him to the minors to see more consistent playing time. The 26-year-old slashed .266/.289/.298 in an injury-plagued 2016, where he was limited to just 25 games at the minor league level.

Vazquez caught for Eduardo Rodriguez in a minor league game Wednesday and helped the left-hander by throwing out two runners trying to steal second base, Peter Abraham of The Boston Globe reports.

These caught base-stealers don't register on Vazquez's official spring stat log, but the backstop has thrown out four of five would-be base-stealers in Grapefruit League play. His ability to control the running game and framing skills are enough to overcome whatever hitting holes he has. If Sandy Leon's hitting anywhere near last year's level (.845 OPS), Boston can maintain Vazquez on the roster. However, if Leon (career OPS .681) turns back into a pumpkin, the Red Sox would be in a position to call up Blake Swihart from Triple-A Pawtucket. In that case, there would be a roster squeeze, with neither Vazquez or Leon having any minor league options remaining.

Perez (elbow), who is serving as the team's DH for Wednesday's Cactus League game against the Padres, is expected to catch in games Friday and Saturday, Rustin Dodd of The Kansas City Star reports.

Perez hurt his knee during a collision at home plate during the World Baseball Classic, but that injury is no longer a concern, and it's instead a hyperextended left elbow that's presenting more trouble at this time. However, it seems he's just about healed up now, and once he gets behind the plate for about six innings in the two games over the weekend, he should be considered ready to go for the start of the season. The Royals are once again preparing to hand Perez one of the heftier workloads at catcher this season, which should help him in racking up counting stats.

Stassi cleared waivers on Tuesday and was outrighted to Triple-A Fresno, Jake Kaplan of the Houston Chronicle reports.

Stassi sits behind Brian McCann and Evan Gattis on the depth chart, so he was always an injury away from cracking the big league roster this season. The 26-year-old was out of minor league options, but the Astros were able to successfully pass him through waivers and keep him in the organization, where he'll head to Triple-A Fresno and serve as catching depth.

Mesoraco acknowledged that he might not be ready in time for Opening Day, the Cincinnati Enquirer reports. "I'm a guy who hasn't played in two years, essentially," Mesoraco told C. Trent Rosecrans. "For me to come out catching one full game and getting 15 at-bats in spring training, that's probably not putting me or the team in the best position. If everybody thinks I'm perfectly ready and ready to go, I'll be in there. If not, it's fine."

Mesoraco has to be treated as a complete wild card in redraft leagues this year, given that he's lost the last two seasons to injury and doesn't appear to be fully ready to start this season. It's not just whether and when he'll play; will he ever recapture the ability that made him valuable in the first place? His hip injury in particular is scary when it comes to generating power.

Perez (knee/elbow) is scheduled to DH on Wednesday and play catch on Friday, Rustin Dodd of The Kansas City Star reports.

This will be his first action back since hyperextending his left knee during a World Baseball Classic game, though the 26-year-old will only be able slot in as the DH due to an elbow injury he's also dealing with. Neither of the injuries is thought to be serious, though, so Perez still expects to be ready for Opening Day.

Leon is hitting just .188 (3-for-16) over seven games, but that's not a concern of manager John Farrell and the catcher remains Boston's presumptive Opening Day starter, Brian MacPherson of the Providence Journal reports. "We've been in a situation where we have rotated three guys in a starting role, so guys have been getting two at-bats every third day," Farrell said. "The offensive evaluation can be a little unfair."

The eye test isn't good for Leon, who has struck out or grounded out in 11 of his 16 spring at-bats. With this coming after a serious September fade in 2016, fantasy owners should treat Leon with circumspection. Red Sox hitting coach Victor Rodriguez echoes Farrell's comments about getting regular at-bats and added that Leon tired toward the end of 2016 under what had been career-high usage. He and Christian Vazquez project to start the season in Boston, but that duo is a potential cipher offensively. The Red Sox may eventually call up a better offensive weapon like Blake Swihart.

Stubbs (shoulder) entered Sunday's game against the Yankees in the seventh inning and caught the rest of the game.

Stubbs developed a shoulder issue early in camp and hadn't gotten into any games until Sunday. His defense is top-notch, particularly in the area of controlling the running game. Developing a competent bat will be a focus over the next 12 months.

Heineman has been sent back to minor league camp, MLB.com's Brian McTaggart reports.

Heineman saw just 11 at-bats this spring, only one of which resulted in a base knock. With several veteran options behind the plate in Houston, it's not too surprising to see the 25-year-old once again fail to break camp. He appears destined for another year at Triple-A, where he slashed .259/.344/.351 over 271 at-bats in 2016.

Plawecki went 2-for-3 with a solo home run, his first of the spring, in Saturday's Grapefruit League game against the Cardinals.

With Travis d'Arnaud catching Noah Syndergaard in a minor league game Saturday, Plawecki got the start for the big league squad and took advantage of his opportunity. He's still likely ticketed for Triple-A Las Vegas to begin the regular season, but d'Arnaud's extensive injury history offers Plawecki a chance for plenty of playing time with the Mets in 2017.
