"I had to keep my mind in the game during the flight, in case we were in extras when I got there and had to pitch," Hughes said Saturday afternoon.
The game, won by the Pirates in the ninth inning on a two-out error by Houston right fielder Jimmy Paredes, was long over by the time Hughes reached the park post-midnight.
If the delay was tough on Hughes -- recalled from Triple-A Indianapolis as Jose Contreras went on the bereavement list -- it was much tougher on Pirates manager Clint Hurdle who, unbeknownst at the time, had a thin bullpen.
"[Jason] Grilli wasn't available, and I didn't want to use [Bryan] Morris," Hurdle said. "We were really hoping Hughes would get here during the game."
Hughes and his improved delivery were at the ready in the Bucs' bullpen Saturday night.
"I definitely made a few mechanical adjustments," said Hughes, who threw all blanks in six outings with Indianapolis after posting a 4.61 ERA in 13 appearances with the Pirates. "I got myself back to where I was when I was really consistent with the sinker and the slider."
"He showed some improvement, although I do think there is more room for improvement," Hurdle said. "But he is better than he was when he got [to Indianapolis]."
