As teams headed down south to the Winter Meetings in San Diego, the two main goals for the A's appeared to be finding a left-handed bat at second base, as well as continuing conversations with relief pitchers.

While the A's didn't make any huge acquisitions during the meetings, the 2019 Rule 5 Draft came and went as it does every year. With that, Oakland selected three players in the minor-league phase of the draft and had a couple more transactions as well.

Second baseman Vimael Machin was acquired from the Phillies for cash considerations. He will be competing for a roster spot.

The 26-year-old slashed .295/.390/.412 with seven home runs and 65 RBI across the Double and Triple-A teams in the Chicago Cubs organization last season.

Jason Krizan was selected from the Mets during the Triple-A phase. The 30-year-old outfielder hit .275 across two teams last season.

The Athletic's prospect writer Emily Waldon says he's going to be a solid addition to the A's organization.

"His walk rate has always been impressive," Waldon told NBC Sports California. "He doesn't have a ton of swing and misses, with some raw power, with eight to ten home run seasons. He's also a dependable defender with a good veteran presence." Waldon also joked Krizan has "80-grade sarcasm."

The A's also selected catcher Jose Colina, who put up some massive numbers with the Arizona League Indians Blue after signing with Cleveland as a minor-league free agent in June. The 21-year-old slashed .372/.443/.744 with eight homers and 20 RBI.

Right-handed pitcher Deivy Mendez rounds the group out. In 25 appearances across Single-A and Short-A last season with the Padres organization, he went 2-1 with six saves and a 4.20 ERA, striking out 33.

The Cincinnati Reds selected outfielder Mark Payton, who was claimed off waivers by the A's in December of 2018. Payton was selected during the major league phase of the draft which, according to Waldon, has the A's losing some muscle at the plate.

However, scouts reportedly didn't see the 28-year-old "doing a great deal outside of filling some needs." That power is what has gotten the most talk around Payton.

Payton took advantage of the PCL last season with Triple-A Las Vegas and slashed .334/.400/.653 with 30 home runs and 97 RBI in 118 games.
