Through the first portion of the Arizona Fall League, left-hander Sammy Solis impressed Nationals scouts and officials, even as Solis’s results disappointed. Friday night, Solis produced an impressive linescore that matched the Nationals’ evaluation.

In his sixth fall league start, Solis, the Nationals’ second-round pick in 2010, gave one of the best starting performances of any pitcher during the fall. Solis struck out nine in four scoreless innings, allowing three hits and three walks. Solis has not allowed an earned run in his last two starts, a span of eight consecutive innings.

Because of several injuries, including a groin strain that delayed the start of his season, Solis only reached Class A Potomac this season, throwing 96 2/3 innings. Solis, a 6-foot-5 left-hander, has been hitting 94 miles per hour with his fastball regularly in the fall league and has reached 97. Overall, Solis has a 4.30 ERA in 23 innings with 23 strikeouts and 14 walks.

The AFL’s Rising Stars game will be played tonight at 8:10 and will be broadcast live on MLB Network. Bryce Harper will play and enter on a 13-game hitting streak. In his last 10 games, Harper is hitting .462/.532/.974 with six homers. He is, it seems, feeling under the weather, though.

Catcher Derek Norris will also play in the Rising Stars game. He’s hitting .339/.443/.482 during the fall league and has impressed Nationals officials with his defensive improvement.
