Dice-K has allowed two hits in his last 15 innings of work - MLB

For Red Sox starter Daisuke Matsuzaka, the 2011 regular season has already been a roller coaster ride.

Dice-K allowed six hits, three walks and three earned runs over five innings in his first start of the year against the Indians. He lasted only two frames next time out against the Rays, surrendering seven earned runs in a messy 16-5 loss.

There was talk after those first two starts that the Red Sox might replace Matsuzaka in their starting rotation temporarily — or permanently.

Oh, how times have changed.

The 30-year-old Tokyo native shut out the Angels over eight impressive innings on Saturday night in Anaheim and has given up just two hits, zero runs and four walks in his last 15 innings of work.

To say that Matsuzaka has figured it all out would be a bit of an overreaction, but he’s clearly doing something right. And with that batting lineup, all Boston really needs is for him to eat some innings this year.

Houston Astros star Jose Altuve had surgery Wednesday on his broken right thumb, an injury that occurred in the World Baseball Classic and will significantly delay the second baseman’s 2023 debut.

The Astros announced that the 32-year-old Altuve had the procedure done in Houston and will stay there to begin his rehabilitation, with only one week left in spring training. The Astros will fly there on Sunday following their final Grapefruit League game in Florida, before playing a pair of exhibitions against their Triple-A team, the Sugar Land Space Cowboys, in Texas.

Altuve was hit by a pitch on Saturday while playing for Venezuela in the WBC. He might not be ready to return to the lineup until at least late May. The eight-time All-Star and 2017 American League MVP batted .300 with 103 runs, 28 homers and 18 steals for the World Series champion Astros last season. Mauricio Dubón and David Hensley are the leading candidates to fill in for Altuve at second base.

Altuve isn’t the only Major League Baseball star who was hurt in WBC play, of course. Mets closer Edwin Díaz will miss the 2023 season because of a torn patellar tendon in his right knee as the freak result of an on-field celebration following a WBC win by the Puerto Rico national team.

BROWN DOWN

The Astros also scratched right-hander Hunter Brown from his scheduled start Wednesday against the Mets in Port St. Lucie, Florida.

Manager Dusty Baker told reporters that Brown, who is ranked by MLB as the organization’s top prospect and competing for the last spot in the rotation, has discomfort in his lower back.

NOT QUITE READY

The New York Mets sent catcher Francisco Álvarez to Triple-A Syracuse, quashing for now the possibility of putting the prized 21-year-old on the opening day roster.

Álvarez, who made his major league debut with the Mets near the end of last season, had just three hits in 28 at-bats in Grapefruit League exhibition games. Ranked by MLB as the third-best prospect in baseball, Álvarez batted .260 with 27 homers and 78 RBIs in a combined 112 minor league games in 2022 at Double-A and Triple-A.

The Mets have newcomer Omar Narváez, a 2021 All-Star with the Milwaukee Brewers, as their primary catcher with Tomás Nido likely to play mostly against left-handed pitchers.

Speaking of the Mets, Díaz turned 29 on Wednesday – a rather subdued milestone for the right-hander considering his situation. Diaz nonetheless posted in Spanish an upbeat message on his Twitter account, thanking God for another year of life and describing his health as good and his outlook as positive in this initial stage of the roughly eight-month rehabilitation process.
