Jon Niese leaves game with rapid heart beat

Jon Niese left this afternoon’s game for precautionary measures with a rapid heart beat.

Niese allowed two runs in 5 2/3 innings against the Rangers, walking two and striking out seven, although he allowed two solo home runs.

Niese expects to be examined on Tuesday when the team is in Detroit, but basically told reporters he is not concerned.

Today in Arlington, Texas, temperatures were in the upper 90s with a heat index over 100 degrees.
