Washington Nationals

Probably due to last week's brief power spike, in which he hit four homers in three games, and a 16-game hitting streak, Fantasy owners have made Adam LaRoche the third-most added first baseman on CBSSports.com, trailing Mitch Moreland and Brandon Belt.

With a batting average that still stands at just .219, LaRoche could still improve, yet he may actually be overowned right now.

Owners in 70 percent of our leagues are rostering LaRoche, and while he should be due for more hits in general and more doubles in particular, when the dust settles, he could easily remain outside the top 25 first basemen. LaRoche has been limited to three doubles in part because of apparent bad luck (1 for 31 on flyballs in play), but he is also striking out far too often. Even as he has heated up in May, LaRoche has 20 strikeouts in 65 at-bats this month.

Power binges come and go, but unless LaRoche starts making contact more often, the Nationals' first baseman may not help much beyond home runs and walks.

Nationals closer Rafael Soriano struggled yet again Tuesday against the Giants, blowing his second save in as many appearances.

Soriano entered the ninth inning of the game with a 2-1 lead and promptly allowed an infield single to let the tying run on base. He got the next two batters out and seemed to be on his way to the save, before allowing a game-tying triple to Gregor Blanco.

Soriano finished the inning without any more damage, but he blew his third save in 15 appearances. The Nationals would lose the game, 4-2, in 10 innings. Soriano has a 2.25 ERA in 20 innings of work. 

Nationals starting pitcher Stephen Strasburg was at the top of his game Tuesday against the Giants, but it was not enough to get him a win, thanks to the team's bullpen woes.

Strasburg pitched seven strong inning in the game, the third time in his last four starts he has gone at least seven innings. He held the Giants to just one run on five hits and three walks while striking out seven batters. He had nine groundball outs to just four fly ball outs, and allowed only singles in the outing.

Unfortunately, his strong effort was wasted, as the Nationals' bullpen allowed three runs in 2 1/3 innings, in a 10-inning, 4-2 loss. Strasburg remains 2-5 on the season, with a 2.66 ERA.

Strasburg will try to get back on the winning side in his next outing, scheduled for Monday against the Rays. 

Nationals pitching prospect Sammy Solis made his first appearance since Tommy John surgery Tuesday, for Class A Potomac. Solis allowed two runs on one walk and three hits in two innings of work in the outing. He worked in the low 90's with his fastball according to MASNSports.com. 

Solis, 24, has not pitched since 2011, when he posted a 2.72 ERA at Potomac. He is a former second-round pick out of the University of San Diego. 

Nationals catcher Kurt Suzuki pushed his hitting streak to 10 games Sunday against the Padres. He doesn't have a multi-hit game during his streak, however.

Suzuki is batting .303 (10 for 33) with one double, two RBI, two runs and two walks in his last 10 games (nine starts).
