May 19: Teams inquiring about A's rookie closer Miller

There hasn't been a better relief pitcher this season than A's fireballing right-hander Mason Miller. He leads all relievers with 1.3 fWAR. He's allowed only two runs and racked up 38 strikeouts through 18 1/3 innings. He has given up one hit over his past 11 outings. He faced 43 batters during that span and struck out 30 of them.

Miller, 25, won't be eligible for arbitration until 2026. He's under club control through 2029. He could be a big piece of the A's future. Or perhaps the club will trade him while his value is sky-high.

As Ken Rosenthal reported for The Athletic (subscription required), teams have contacted the A's in the interest of making a deal for Miller, and Oakland will not rule out trading him before the July 30 Trade Deadline. But Miller, whose fastball averages an MLB-best 100.9 mph, won't come cheap.

"To acquire him, a team likely would need to give up a young player of comparable ability, or a substantial package of multiple youngsters who could be part of the A’s future," Rosenthal wrote. "Thus, if the Padres wanted Miller at this early stage, the A’s likely would ask for rookie center fielder Jackson Merrill. Other teams would be hit with similar requests."

Miller, who can reach 103 mph on the radar gun, did miss almost four months during his debut 2023 season with a sprained right elbow. And a reliever's performance can vary widely from year to year. Yet that apparently hasn't stopped clubs from expressing their desire to get him.

May 19: Astros' Bregman seen as likely trade candidate by MLB execs

MLB.com's Mark Feinsand recently posed the following question to two dozen front-office executives: Who will be the biggest name moved by the July 30 Trade Deadline? Sixteen players were mentioned, but none more often than Astros third baseman Alex Bregman.

"If [the Astros] are out of the race, he could be a difference-maker for another contender," a National League executive said of Bregman, who was named by five of the 24 participating executives.

The execs were polled prior to the Astros' six-game winning streak, which came to an end Saturday. Even after this run, Houston sits at 20-26. It is five games behind the Mariners in the AL West and 4 1/2 games back of the final Wild Card spot. The Astros entered Sunday as winners in eight of their past 10 games, and Bregman has batted .333 with three homers and a 1.008 OPS over that stretch. Prior to that, he slashed just .189/.268/.252 through 33 games.

The 30-year-old Bregman is in the final season of a six-year deal. He may not be the only Astro headed elsewhere if the club can't fully recover from its poor start. Feinsand included relievers Ryan Pressly and Kendall Graveman as possible trade chips. Others include Kyle Tucker, Framber Valdez and Jose Urquidy, all of whom have one year of club control remaining after this season.

May 19: Will Blue Jays trade Gausman?

“We are not where we would like to be."

That's how Blue Jays general manager Ross Atkins described the team's position on Saturday before a loss to the Rays dropped Toronto to 19-25. It is in last place in the AL East, 11 1/2 games behind the Yankees and 4 1/2 games out of the final Wild Card spot.

If things don't turn around soon, the Blue Jays will be faced with a lot of decisions on what to do with players who are nearing free agency. Headline stars Bo Bichette and Vladimir Guerrero Jr., both under contract through 2025, are at the top of that list. Starting pitcher Yusei Kikuchi, reliever Yimi García and third baseman Justin Turner could be more readily available if the Blue Jays choose to sell as those three are free agents at the end of this season.

But what about ace starter Kevin Gausman? An AL Cy Young Award finalist last year, he is under contract through 2026. While The Athletic's Ken Rosenthal recently said that he doesn't expect a deal for Gausman to materialize, he also didn't rule out the possibility that it could happen.

"If you're going to make a trade, who better to trade than Kevin Gausman?" Rosenthal said.

Gausman's preparation for this season was interrupted in March by a case of right shoulder fatigue. Although he made his season debut before the end of the month, the 33-year-old hasn't been able to replicate his 2023 success. He owns a 4.89 ERA through 42 1/3 innings, and his strikeout rate has declined nearly nine percentage points from last year, down to 22.6%.

May 19: Greinke contemplating comeback, working out at D-backs facility

Is Zack Greinke's MLB career over? He's not sure yet. But he's preparing as if he has something left to give the game.

The 40-year-old is working out at the Diamondbacks' Spring Training facility in Scottsdale, Ariz., while mulling over what he wants to do. He threw a live batting practice session against some D-backs hitters on Friday. The six-time All-Star isn't negotiating with Arizona or any other team at the moment; the D-backs are simply allowing him to use their facility while he considers his next steps.

"My arm feels decent at the moment,” Greinke told Nick Piecoro of the Arizona Republic. “I was trying to get as good as I could at golfing the past two months, and I was like, ‘Why am I trying to be a pro golfer when I’m already kind of a pro baseball player?’ So I figured I’d throw a little and see how it goes. ... I don’t know if this will be my last time throwing or if I’ll throw the rest of the year and next year. I don’t really know at the moment."

Greinke posted a 5.06 ERA over 142 1/3 innings with the Royals last season, his 20th in the Majors. And he may not be the only 40-something pitcher to land with a team midseason; 44-year-old lefty Rich Hill told MLB.com earlier this month that he plans on joining a roster once he is done coaching his son's Little League team.
