Pat Venditte is one of the first arrivals in a swarming A’s clubhouse each morning, and he’s proud to share the story of how he became an ambidextrous pitcher, a tale that’s just as amazing as the people behind it.

Shrewd fantasy owners will be watching key position battles this month in order to understand the depth charts of all the teams. Following is a look at the 10 battles that owners should give their closest attention.

Alex Rodriguez knocked in his first run of the spring, and Michael Pineda and Nathan Eovaldi had strong outings on the mound in the Yankees’ win over the Rays.

Nationals left-hander Gio Gonzalez started his first game of the spring and pitched two scoreless innings. The outing meant Gonzalez didn’t have any problems with his shoulder, which caused him to miss a month of the 2014 season.

Cardinals right-hander Lance Lynn received good news after an MRI performed on Monday confirmed that he had not suffered anything more serious than a left hip flexor strain in his start on Sunday.

To Mat Latos, it didn’t matter if it was on a back field at Roger Dean Stadium in Jupiter, Fla., or on the mound at Tradition Field. Just facing hitters was a nice starting point for the Marlins right-hander. Latos threw two innings on Monday morning in a simulated game at the Marlins complex, and he’s progressing toward making his Grapefruit League debut, perhaps as early as the end of the week.

Jose Valverde hasn’t been an impact pitcher in the big leagues since 2012. But the 36-year-old is in Padres camp on a Minor League deal, and the three-time All-Star reliever is beginning to show that he still has something left in the tank.

Eric Young Jr.’s two-run homer proved to be the difference as the Braves beat the Nationals, 2-1, at Space Coast Stadium on Monday afternoon. Wandy Rodriguez pitched three scoreless for Atlanta.

Andres Blanco homered to lead the Phillies to a 1-0 win over the Orioles on Monday afternoon at Ed Smith Stadium. Aaron Harang pitched two scoreless innings in his Grapefruit League debut. He missed his scheduled start last week because of lower back tightness. He said the issue is behind him.

Michael Wacha tossed two perfect innings in the Cardinals’ 3-0 loss to the Red Sox on Monday at Roger Dean Stadium.

A two-run seventh featuring RBI hits by Luke Montz and Mookie Betts propelled the Red Sox to a 3-0 win over the Cardinals on Monday in their first Grapefruit League meeting of the spring.

When Dexter Fowler was a rookie with the Rockies, he remembers being razzed all the time by the veterans in the clubhouse. The Cubs’ Kris Bryant is different. Fowler is stationed next to Bryant in the Cubs’ clubhouse, and the No. 2 overall prospect in baseball, per MLB.com, noted that the veteran is always giving him a hard time, although it’s all good-natured.

At least for pregame batting practice, the Tigers are pretty close to full strength. Victor Martinez joined Miguel Cabrera on the field Monday, taking BP with the team for the first time this spring.

While Dodgers management backs away from any implication that 18-year-old pitcher Julio Urias is ready for the Major Leagues, that’s not the case with 20-year-old shortstop Corey Seager.

Miguel Sano picked on Gerrit Cole’s first pitch to him in the second to send it onto the left-center boardwalk against the wind. It was the first spring homer for Sano, rated MLB.com’s overall No. 4 prospect a year ago before losing the entire 2014 season to Tommy John elbow ligament replacement surgery. He’s now ranked No. 11 by MLB.com.

The Bucs had grabbed a 1-0 lead in the first on two-out doubles off Ricky Nolasco by Andrew McCutchen — his first hit of the spring — and Neil Walker.

A new Major League Baseball season begins next month, and for the first time you will be able to follow what happens on a wearable device.
