Worth noting

• Hurdle did not expect to have either Alvarez or Snider available Sunday against the Reds. Snider has been held out of the lineup in three straight games after tweaking his left hamstring on the basepaths Wednesday afternoon.

Meanwhile, it's the fourth game in a row Alvarez is not starting, as he sprained his left foot diving for a ball Tuesday against the Cardinals. Hurdle said the first baseman has hit off a tee, but he has not done much of any other baseball activity.

• Pimentel will be rejoining the Pirates' bullpen soon, Hurdle confirmed Sunday. Pimentel hasn't pitched for the Bucs since Aug. 13 due to a mildly sprained right ankle, but he has made five rehab appearances between Double-A Altoona and Triple-A Indianapolis in the last 10 days. Hurdle said Pimentel may pitch once more for Indianapolis before coming back to the Pirates, but he is on track to return early in the next week.

In those five appearances, the right-hander has given up one earned run, three hits, and he has struck out two and walked four in 5 1/3 innings. In his last outing, Pimentel pitched two scoreless innings and got a save on Friday.

• Hurdle said Charlie Morton will throw a simulated game on Tuesday, as he continues to try and come back from a sports hernia in his right hip. Morton, a right-handed sinkerballer, has been on the disabled list for two weeks and has dealt with the issue since June 2. He threw a 73-pitch rehab start with Double-A Altoona on Thursday, but said he didn't see any noticeable improvement in his recovery.
