• The Cubs dealt left-handed reliever Hisanori Takahashi to the Rockies on Saturday for a player to be named later or cash considerations.

Takahashi, 38, opened the season with the Cubs but after three games was sent to Triple-A Iowa. In 20 games with Iowa, he went 1-0 with a 1.98 ERA, giving up six earned runs over 27 1/3 innings.

• The Cubs will likely make a roster move prior to the start of a six-game road trip against American League West teams. Chicago will travel to Seattle and Oakland, starting Tuesday.

The Cubs are currently carrying eight relievers and are expected to add another position player before the West Coast trip.

• The Elias Sports Bureau says Friday's game, in which the Cubs and Astros combined for four runs all via solo home runs, was the first contest in Chicago's 98 seasons at Wrigley Field in which both clubs combined to score at least four runs and all the runs in the game were scored on solo homers.

• Kevin Gregg has converted 11 straight save chances to begin the season, the second-longest for a Cubs reliever, surpassed only by Randy Myers, who saved his first 13 chances to open the 1993 campaign.

• A group of 24 kids, ages 7-14, will participate Sunday in the Chicago Cubs championship of the 2013 MLB Pitch, Hit and Run (PHR) program presented by Scotts, at Wrigley Field. The top three scores in each age and gender group out of all 30 MLB Team Championships will advance to the PHR National Finals held at Citi Field in New York City during MLB All-Star Week. Pitch, Hit and Run provides youth with the chance to demonstrate their skills and advance through four levels of competition, beginning at the local level.

• The Cubs signed their sixth-round Draft pick, right-handed pitcher Scott Frazier from Pepperdine University. Additionally, the Cubs signed their 17th-round selection, first baseman Kelvin Freeman from North Carolina A&T University. So far, Chicago has signed 13 players from the First-Year Player Draft, including three top-five picks and six top-10 selections.

Frazier, 21, recently completed his junior season at Pepperdine, going 5-5 with a 4.06 ERA and a team-leading 83 strikeouts in 88 2/3 innings. He held opponents to a .237 batting average and allowed just nine extra-base hits. He finished the campaign 2-0 with a 1.29 ERA and 24 strikeouts in his final three starts.
