Fantasy Baseball Player News

Moises Ballesteros, Chicago Cubs

Chicago Cubs catcher Moises Ballesteros is quickly making a name for himself with the way he has been swinging the bat. Through 35 games this season, Ballesteros is slashing .277/.340/.521 with six home runs, 19 RBI, and 10 walks.

He has fallen into a cold spell recently, going 3-for-36 over the last two weeks. Despite some struggles, Ballesteros is worth rostering in deep leagues at the minimum. He offers offensive upside at the plate that other catchers can't match. Fantasy managers might have to go through some growing pains, but his overall upside will be worth it.

Bryce Harper, 1B, Philadelphia Phillies

Philadelphia Phillies first baseman Bryce Harper (head) is back in the starting lineup and is hitting third for Sunday's series finale against the visiting Colorado Rockies and right-hander Tomoyuki Sugano, according to MLB.com. Harper was pulled from Saturday's win over Colorado before even making a plate appearance due to a migraine, but he's feeling much better on Sunday and will return to action.

Fantasy managers will want to get him back into their lineups in traditional leagues. The 33-year-old two-time MVP and eight-time All-Star is hitless in three career at-bats against Sugano, but he's been hot so far in May with a .357 average (10-for-28) with three home runs, three doubles, four RBI, eight runs scored, and a stolen base in 34 plate appearances across nine games. Overall, it's been a productive season for Harper, as he's slashing .282/.380/.549 with a .929 OPS, nine home runs, 23 RBI, 24 runs scored, and two stolen bases in 142 at-bats.

Miguel Vargas, Chicago White Sox

Chicago White Sox third baseman Miguel Vargas led the charge in the team's 6-1 win over the visiting Seattle Mariners on Saturday, going 2-for-3 at the plate with two home runs, three RBI, a walk, and a strikeout to raise his season average to .228 and his OPS to .840. Vargas' two home runs came against Luis Castillo and Josh Simpson. It was the 26-year-old's first multi-homer game of the season.

Although the Cuban infielder is still hitting just .228 (31-for-136) on the year, he's making more consistent contact at the plate than he ever has before. He's up to nine home runs on the season and has added 21 RBI, 28 runs scored, and six stolen bases in his 38 games played in his second full season with the Pale Hose. In 11 games since April 27, Vargas has gone 11-for-38 (.289) with four long balls, eight RBI, eight runs scored, and a stolen base across 47 plate appearances. He's heating up and remains a useful corner-infield power bat in deep-mixed fantasy leagues.
